 Fire as a natural environmental regulator of animal populations particularly 

 insects, has certainly been long overlooked. The selected and incomplete 

 literature review indicates not only a basis for insect control but also the 

 need for studies in the fire ecology of insects in this region. The effect 

 of fire in its intricate relationships with insects, if known, might well 

 become important as an ecological control of insects by habitat management.

 tions of cotton insects in Arizona. J. Econ. Entomol. 65: 855-860. 



Enumeration samples of various insects associated with cotton were collected 

 over a S-year period in commercial cotton fields to evaluate their statistical 

 properties. Samples from relatively low-density populations agreed with Poisson 

 expectations while samples indicating relatively dense insect populations agreed 

 with expectations of the negative binomial distribution. The number of plants 

 per sample unit influenced the statistical distribution of the samples. Cotton- 

 insect populations tend to be clustered, but the clustering is detected only 

 under very intensive samppling or when {population density is high. Several 

 J?iological, models can lead to the same statistical properties of the sampling 

 distributions.

 and influence of ingested chemosterilized boll weevils on reproductive 

 performance of the Japanese quail. J. Econ. Entomol. 66: 341-343. 



Busulfan-sterilized males of Anthonomus grandis Boheman were released in cotton 

 fields of south Mississippi, Alabama, and Louisiana as part of the boll weevil 

 eradication experiment. Laboratory experiments were conducted on the Japanese
